Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To speed up generation of a pumping clock when a decline in step-up voltage is detected, by connecting an output terminal and a control terminal of a voltage detecting means by a second capacitor. SOLUTION: When a voltage detecting circuit 1 detects a decline in step-up voltage VXD, it turns a detection signal OSUP to a high level, thereby turning an NMOS transistor 4, a PMOS transistor 6, and a transfer gate 7, fixing a connection 10 to the ground potential, and fixing a connection 13 to the supply voltage. Then, simultaneous with turn-off of an NMOS transistor 8 and a PMOS transistor 9 the voltage at a connection 14 is temporarily raised by a coupling capacitor 15 to prevent the decline in voltage. When the voltages at the connections 14, 13, 10 reach a value determined by the drain voltage of the PMOS transistor 6 and the voltages of current controlling sections 11, 12 a ring oscillator 3 rapidly outputs a first pumping clock VBOS to a pumping step-up section 2.
